Answer:
The values of x and y that satisfy the equation are 2 and 2, respectively.
Step-by-step explanation:
Two complex numbers are identical if and only each pair of respective coefficients are identical on both sides. Then, we need to observe the following conditions:
Real component
[tex]4\cdot x = 8[/tex] (1)
Imaginary component
[tex]2 = y[/tex] (2)
The solution of this system of equations is [tex]x = 2[/tex] and [tex]y = 2[/tex].
The values of x and y that satisfy the equation are 2 and 2, respectively.
The values of x and y that satisfy the equation is x = 2, y = 2.
Given that,
The equation is 4x+2i=8+yi.Based on the above information, the calculation is as follows:
Here two complex numbers are the same and for one pair with respect to the coefficient should be same on the both sides.Now
(4) (x) = 8.........real component
x = 2
And,
2 = y..... imaginery component
Therefore we can conclude that the values of x and y that satisfy the equation is x = 2, y = 2.

What are the coordinates of the circumcenter of this triangle?
Enter your answer in the boxes.
Answer:
The coordinate of the circumcenter of the given triangle is (4, -1)
Step-by-step explanation:
The circumcenter is found by the intersection of the perpendicular bisectors of a triangle as follows;
The vertices of triangle ΔABC are A(1, 1), B(1, -3), and C(7, -3)
The coordinates of the midpoint of segment AB is 1/2(1 + 1, 1 + (-3)) = (1, -1)
The slope of segment AB = ∞, therefore, the slope of the perpendicular to segment AB = -1/∞ = 0
The line representing the perpendicular to segment AB is y = -1
The coordinates of the midpoint of segment BC is 1/2(1 + 7, (-3) + (-3)) = (4, -3)
The slope of segment BC = 0, therefore, the slope of the perpendicular to segment BC = ∞, which is a vertical line parallel to the y-axis with equation, x = 4
Therefore, the coordinate of the circumcenter is the intersection of the lines y = -1, and x = 4, which is the point (4, -1).

A two digit number exceeds the sum of the digits of that number by 18. If the digits at the unit's place is double the digit in the ten's place, find the number
Answer:
The number is 24
Step-by-step explanation:
Let the two digits number be ab
In real terms, this is 10a + b
So, we have that the sum of the digits subtracted from 10a + b is 18
Mathematically, we have this as;
10a + b - (a + b) = 18
10a + b - a - b = 18
9a = 18
a = 18/9
a = 2
We are also told that the digit at the units place b is double the digit at the ten’s place a
That means b = 2a
b = 2 * 2 = 4

I hope this helped and if it did I would appreciate it if you marked me Brainliest. thank you and have a nice day!
Answer:
0.05
Step-by-step explanation:
40 x 10 = 400
2 x 10 = 20
400 ÷ 4 = 100
20 ÷ 4 = 5

For the straight line defined by the points ( 3 , 51 ) (3,51) and ( 5 , 87 ) (5,87) , determine the slope ( m m ) and y-intercept ( b b ). Do not round the answers.
Answer:
Intercept = - 3 ; slope = 18
Step-by-step explanation:
Given the points :
(3, 51) ; (5, 87)
x1 =3, y1 = 51, x2 = 5 ; y2 = 87
Slope intercept relation:
y = mx + c
m = slope ; c = intercept ; x and y are x, y vlayes respectively
Slope (m) = (y2 - y1) / (x2 - x1)
Slope (m) = (87 - 51) / (5 - 3)
Slope = 36 / 2
Slope (m) = 18
The intercept c :
m = 18 ; x = 5 ; y = 87
Substitute values into the slope intercept formula :
87 = 18(5) + c
87 = 90 + c
c = 87 - 90
c = - 3
Intercept = - 3

What are the missing values in the table?
Answer:
B: A = –5x; B = –1x; C = 5
Step-by-step explanation:
The missing values in the division table are as column (A): –5x; column (B): –1x; column (C): 5. The correct answer is option B.
To fill in the missing values in the division table, we need to perform polynomial long division to divide the dividend [tex](x^{4} - 4x^{3} + 4x^{2} - 6x + 5)[/tex]by the divisor (x – 1).
The quotient and remainder will help us complete the table.
Performing the polynomial long division, attached below image.
From the division, we can determine the values for the missing cells:
Divisor: x - 1

Given the function g(x) = 3x – 1, find x if g(x) = –19.
Answer:
x = -6
Step-by-step explanation:
If g(x) = -19, then -19 is 3x - 1 since g(x) = 3x - 1.
So, we get the expression -19 = 3x - 1.
Add 1 on both sides: -18 = 3x
Divide both sides by 3: -6 = x

A sector with an area of \goldE{26\pi\,\text{cm}^2}26πcm 2 start color #a75a05, 26, pi, start text, c, m, end text, squared, end color #a75a05 has a radius of \maroonD{6\,\text{cm}}6cmstart color #ca337c, 6, start text, c, m, end text, end color #ca337c. What is the central angle measure of the sector in radians?
Answer:
13π/9 rad
Step-by-step explanation:
Given the following
Area of a sector = 26πcm²
radius of the sector = 6cm
Required
central angle measure of the sector in radians
Area of a sector = Ф/2π * πr²
26π = Ф/2π * πr²
26 = Ф(6)²/2π
26 = 36Ф/2π
2π = 36Ф/26
π = 18Ф/26
26π = 18Ф
Ф = 26π/18
Ф = 13π/9 rad
Hence the measure of the central angle in radians is 13π/9 rad
